Everyone uses HDPARM to tweak their IDE drives. Are there any utilities to do so with SCSI drives? Granted, some things just don't apply to SCSI, but I am sure something is tweakable. I'm not sure how accurate HDParm is as a benchmark, but currently I get from "hdparm -tT /dev/sda":

I've seen this asked a few times, and have yet to get an answer. The best I've seen is implementing TCQ, but that should be done already.

You're getting excellent results... I have a 15k rpm Cheetah, and you're still over 10 MB above me for unbuffered. My buffered reads tend to be around 260MB, though._________________Gentoo, Gnome, and LaTeX. What more do you need?
